Deterministic/byte-reproducible incl. FNV; verify.sh passes ~15s; chunks regenerate byte-identically. NIT (non-blocking): verify.sh's straggler reconciliation key drops chunk identity and REAL cross-chunk family collisions exist (234431 x4, 179783 x3, 6731 x2) -- so that step is weaker than its comment; check_witnesses.py's size-10 top-tree isomorphism check backstops it and the true chunk-aware 1:1 correspondence is exact (referee-verified). Fix: re-key on (top_index, fam_counter, idxs).

Referee model-diverse blind panel (opus/sonnet/haiku) + review-lead's own DISJOINT witness re-verification + referee audit. CALL: GREEN. The green path for a witness/exhaustive result -- disjoint re-verification of the constructed witnesses with an own checker + independent confirmation of the enumeration/search-space bound -- was met in full: an independent checker sharing no code with the author's search or validator (own canonical form + VF2, distinct from the author's AHU) validated every packing in TWO ENTIRE chunks, the ENTIRE non-greedy population across all 106 chunks (1,584,807 witnesses, 0 failures), and all 27 CP-SAT stragglers; exhaustiveness was independently re-proven (VF2 non-isomorphism + A000055 + per-chunk full-Cartesian coverage + the symmetry lemma). Re-running the packer only regenerates witness DATA, which the disjoint checker then validates -- disjoint reproduction, not rerun-trust. The disclosed positive/witness-only residual (the full 45M archive isn't stored; greedy families outside fully-checked chunks rest on deterministic regeneration + edge-disjoint-by-construction) does not block green -- the regenerate-> disjoint-check pipeline was demonstrated sound on 2 full chunks + the entire high-risk non-greedy set. Honestly scoped ('exhaustively verified for n=10'; conjecture remains open). Non-blocking nits handed back: verify.sh reconcile key (re-key on chunk id), a constructed-at-runtime vs independently-re-checked framing distinction, and an attribution drift.
